Reaching Progan

Without the need of discussing the plan with the others, the acting leader stepped up and dived into the horde himself. He compressed and hardened his Aura around his entire body, forming a shell-like membrane that protects him from the monsters' attacks. 

If he was fighting against someone or something that has a similar level of power as him, the protective Aura membrane would've been easily penetrated or even shattered. But as the monsters were weaker than him, the protective membrane worked perfectly.

He swept through the horde, killing everything in sight until he reached the two 3-star monsters. The acting leader swung his sword, but as he expected, because of his exhaustion from mowing down the monsters earlier together with the others, he wasn't able to deal a finishing blow despite being stronger than a 3-star monster.
